Disgusting Service

I am very disappointed in he service I have received thus far from FNB, from the branch to their call centre and their complaints department. I logged a complaint via their website on the 16/11/2018 and I was sent a ref via email. On the 18/11/18 i received a call from a rude lady, who asked me which branch did I go to, I then asked her if she will be handling my query, she then rudely told me that she is just calling to find out which branch did I go to. A week later I decided to contact the complaints department on the number that was provided on the email that had my ref number, the number did not go through, I then sent an email, which to date I haven't received any response. I contacted the call centre, the credit department, my call got through to Muneera ***aine, who was rude and was not bothered, she just gave me the complaints department's email address after i have told her several times that I have sent an email already and there was no response, I then requested to speak to her supervisor, the supervisor came to the phone, her name is Kamini Lingham. the supervisor was also no help at all and she then asked me to call Discovery as this is not their query. The service is very disgusting, I just want to move my accounts to a different bank and i will tell my family and friends to cancel their accounts with FNB.
